Hey everyone - I'm questioning whether my fatigue, lightheadedness, and poor stamina are due to POTS (not enough blood to my brain), hypometabolism (specifically a deficiency in TCA enzymes or glycolysis) , elevated TNFa (from fighting pathogens), or all of the above. Genova NutraEval seems to indicate some dysfunction, but UCLA Urine Organic Acid testing appears normal (although metabolite levels have fluctuated). Given that UCLA is a highly rated research university I'm inclined to trust their results, but they don't test as many metabolites as Genova. Both seem to show I'm in ketosis which makes sense given my diet. Any help on squaring and contextualizing these results would be greatly appreciated. ARUP August Cytokine panel TNFa - 78 (ref <=22) UCLA Lactic / Pyruvic Ratio: Lactic Acid 1.68 / Pyruvic Acid = 0.146 UCLA Urine Organic Acid results over time: UCLA Plasma Amino Acid results over time: NutraEval from June Tagging some knowledgeable folks: @Hip @alicec @Freddd @caledonia @halcyon @Learner1 Thanks!
